The reason for me posting this is that, still not having a licence, I restrict myself to listening. I try to listen to as much as possible, in different “modes”. At some point of course I came across APRS. From everything I have read across the internet there is one single de-facto standart software that decodes the data packages and displays them on screen. That one software needs a software-licence that is only available to licenced-amateur-radio-operators. Which is pretty bad, if you just want to listen, like me. Well Asking around in a german HAM-Radio internet forum, telling in the entry post that I have no access to that software, I got recommended to use it 3 times within the next 5 posts. Embarrasing…

Another amateur radio video. Actually the best thing I ever saw explaining a directional antenna visally. Simple experimentation like this is way better than any written description or even simulations and graphics.
